ABSTRACT
Objective To explore the accuracy and practicability of the three-dimensional ultrasound in real-time intellectual positioning navigation.Methods The phantom was applied in the real-time intellectual positioning guided biopsy of three dimensional ultrasound,free-hand ultrasound-guided biopsy and bracket-guided biopsy with different depths(5 cm,10 cm) and different sizes of the targets (6 mm and 15 mm).The time spent,the length of the sample and the success rate of biopsy were compared among three groups,and statistical analysis was done.Results ①The different sizes of targets with different depths were shown in three kinds of biopsy that the real-time intellectual positioning guided biopsy of three-dimensional ultrasound spent more time than bracket-guided biopsy,less than free hand ultrasound-guided biopsy.The difference was significant (P <0.05).The aquired red-dyed sample was longer in the real-time intellectual positioning guided biopsy of three-dimensional ultrasound compared to free-hand ultrasound-guide biopsy and bracket-guided biopsy,the difference was significant (P <0.001).②For real-time IP-guided biopsy of three-dimensional ultrasound with same depth,larger size of targets(15 mm) spent less time than smaller saize of targets (6 mm),the difference was significant (P < 0.05).However,compared to smaller saize of targets(6 mm),success rate of biopsy in larger size of targets(15 mm) had no significant difference (P =0.238 at depth of 5 cm,P =0.479 at depth of 10 cm).③For real-time intellectual positioning guided biopsy of three-dimensional ultrasound with same size,time spent was less in the targets at the depth of 5 cm than in the targets at the depth of 10 cm,the difference was significant (P<0.05).The aquired red-dyed sample was longer in the targets at the depth of 5 cm than in the targets at the depth of 10 cm,and success rate of biopsy in the targets at the depth of 5 cm was higher too (P <0.05).Conclusions The real-time intellectual positioning guided biopsy of three dimensional ultrasound spend less time with high accuracy and success rate of biopsy,especially for smaller and deeper targets,can be clinically applied with accuracy and practicability.
